What term refers to the use of Earth's renewable and nonrenewable resources in ways that do not constrain future resource use?

• A. Global Positioning System
• B. Land use
• C. Sustainability
• D. Site

Answer: (C)

Sustainability is the idea of using Earth's resources in a way that doesn't limit the ability of future generations to meet their needs. It focuses on maintaining natural capital—like forests, minerals, water, soils, and biodiversity—while still supporting current well-being. In practice, this means pursuing energy efficiency, using renewable resources, recycling, and protecting ecosystems so resource bases remain viable over time. The other terms don’t capture this long-term balance: GPS is about finding locations, land use is about how land is designated and managed, and site refers to a place.
